What is a significant consequence of plaque accumulation?

Plaque accumulation on teeth is a significant factor that leads to a variety of oral health issues. When plaque, a sticky biofilm of bacteria, is left on the teeth, it can lead to dental caries, which are cavities caused by the acids produced by bacteria as they metabolize carbohydrates. Additionally, plaque is a major contributor to gingivitis, an inflammation of the gums characterized by redness, swelling, and bleeding. If left untreated, gingivitis can progress to periodontal disease, which involves the loss of supporting bone and gums surrounding the teeth.

The presence of plaque makes it significantly more challenging to maintain oral health, as it fosters an environment where harmful bacteria thrive. This cascade of problems stemming from plaque accumulation illustrates the importance of regular dental hygiene practices to prevent these serious conditions. The other options listed are also associated with plaque, but they are often seen as consequences of the more severe conditions prompted by plaque buildup.
